How much of my income should disability insurance replace?

Most financial planners recommend replacing 60–70% of your gross income. Benefits are often tax-free when you pay the premiums yourself, so 60% of gross can equal close to your net take-home pay.

What is the difference between short-term and long-term disability?

Short-term disability typically covers 3–6 months after a brief elimination period (0–14 days). Long-term disability kicks in after a longer elimination period (90–180 days) and can pay benefits until retirement age. This calculator focuses on the monthly benefit amount needed regardless of policy type.

What is an elimination period?

The elimination period is the waiting period after disability begins before benefits are paid — similar to a deductible measured in time. Common periods are 30, 60, 90, or 180 days. The longer the elimination period, the lower the premium. Your savings runway result tells you whether your savings can cover this gap.

Does employer coverage count toward my needed benefit?

Yes. Group employer disability plans (usually 60% of base salary) are counted as existing coverage. Enter that amount in the "Existing Monthly Benefit" field. The calculator then shows only the gap you need to fill with an individual policy.

Are disability insurance benefits taxable?

If your employer pays the premiums, benefits are generally taxable. If you pay the premiums with after-tax dollars, benefits are typically tax-free. This changes the effective replacement rate — a 60% gross benefit paid tax-free may fully replace your net pay.

How accurate is this estimate?

This tool gives a planning estimate based on the numbers you enter. Actual premiums and benefit eligibility depend on your occupation, health history, policy definition of disability, and insurer underwriting. Consult a licensed insurance professional for a personalized quote.

Disability Insurance Quick Reference

Replacement Rate

Most policies cover 60–70% of gross income. Benefits paid with after-tax premiums are usually tax-free, making 60% roughly equivalent to your net pay.

Elimination Period

The waiting period before benefits start. A 90-day elimination period means you need roughly 3 months of savings or short-term disability coverage to bridge the gap.

Benefit Period

Short-term policies pay for 3–6 months. Long-term policies can pay to age 65. For maximum protection, pair a 90-day elimination period long-term policy with 3 months of savings.
